Robot Baby Crib By Suima

The Suima robotic crib lovingly (well, mechanically) takes care of your little one. For just $100 per month, you can rent the robotic crib, which has a "baby cry sensor" to determine when rocking is needed.

When rocking is deemed necessary, the Suima robotic crib swings itself back and forth every 1.8 seconds, which approximates (according to the manufacturer) a parent's heartbeat. Maybe it counts each extreme as a beat.

This idea of robots taking care of children may remind readers of the nanny robot from Philip K. Dick's 1955 short story Nanny. However, the earliest science-fictional nanny robot to take care of children, as far as I know, was the psychotronic nurse from David H. Keller's short story of the same name published in Amazing Stories in 1928.

"...When I ordered this machine ... I bought a phonograph with clock attachment. It will run for twenty-four hours without attention. Then I had a baby doctor work out a twenty-four hour programme of infant activity for different ages. Our baby is about two months old. You put this phonograph with the two-month record on it in the nursery... At definite periods of the twenty-four hours the phonograph will call out a number and the nurse will do what is necessary..."

Another neat device that Keller thought of is something that Suima could implement in their robot baby crib - the electric diaper, which senses moisture.
